PLC (Programmable Logic Controller) diperkenalkan pertama kali pada tahun 1969 oleh Richard E. Morley yang merupakan pendiri Modicon Corporation. Menurut National Electrical Manufacturing Assosiation (NEMA) PLC didefinisikan sebagasi suatu perangkat elektronik digital dengan memori yang dapat diprogram untuk menyimpan instruksi-instruksi yang menjalankan fungsi-fungsi spesifik seperti: logika, sekuen, timing, counting, dan aritmatika untuk mengontrol suatu mesin industri atau proses industri sesuai dengan yang diinginkan. PLC mampu mengerjakan suatu proses terus menerus sesuai variabel masukan dan memberikan keputusan sesuai keinginan pemrograman sehingga nilai keluaran tetap terkontrol.
